1 of 1 ZIP code (100%) have recorded EPA violations. 6 health-based violations documented.
Home Safety Score
Average Home Safety Score for Louisiana: C (56/100)
The score combines three factors:
| Factor | What It Measures |
|---|---|
| Water Quality | EPA violations and compliance history |
| Lead Levels | 90th percentile lead concentration vs EPA action level |
| Radon Risk | EPA radon zone classification |
Water Sources
Louisiana water systems draw from: Surface water.
Lead & Copper
- Average lead level (90th percentile): 0.0044 mg/L (EPA action level: 0.015 mg/L)
- 0 ZIP codes exceed the EPA lead action level
Radon Risk
Dominant radon zone: Zone 2 (Moderate Risk)
The EPA recommends testing homes in Zone 1 and Zone 2 areas for radon.

Key Contaminants Detected in Louisiana
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Louisiana's Housing Stock?
With 78% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
When a city's housing median build year is 1964, as in Louisiana, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Louisiana were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Louisiana: Remediation Cost in Perspective
In Louisiana, the remediation-to-property-value ratio is elevated enough that homeowners who identify documented issues early have an advantage — understanding the scope, sequencing by urgency, and phasing the work against household budget capacity are the practical levers that determine whether remediation feels manageable or overwhelming at this equity tier.
At 2.6% of home value, remediation costs in Louisiana represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,400–$4,900. Home values here are 42% below the Missouri average.
Protecting Children from Lead in Louisiana
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 78% pre-rule share in Louisiana keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Climate-Related Water Risk for Louisiana
Flood risk in Louisiana occupies the middle ground: 216 NFIP claims and 100% of local ZIP codes within FEMA flood zones. At that level, the risk pathways connecting flooding to water quality — treatment system stress, well infiltration, distribution backflow — become relevant considerations during significant flood events, even if day-to-day water quality is unaffected by flood history.
Louisiana has a moderate flood history with 216 FEMA claims averaging $12,804 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$2,700</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.

What You Can Do in Louisiana
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. Filters rated for Haloacetic Acids (HAA5) can reduce the most common contaminant found in Louisiana's water.
- Check your home's plumbing. With 78% of homes built before 1986, lead solder is a real possibility.
